Abstract
Description
- This application is a continuation-in-part of U.S. application Ser. No. 15/066,902, entitled “Desiccant Breather”, and filed on Mar. 10, 2016, which claims the benefit of U.S. Provisional Application No. 62/130,616, entitled “Desiccant Breather” filed on Mar. 10, 2015, all of which are incorporated herein by reference in their entirety.
- Embodiments relate generally to desiccant breathers, and more particularly, to desiccant breathers having replaceable desiccant media.
- Some conventional desiccant breathers may require an entire breather assembly to be replaced in order to provide new desiccant media. Still other conventional desiccant breathers may have replaceable media, but may expose protected equipment to the environment during replacement of the desiccant media. Further, desiccant breathers that require replacement of an entire assembly may also expose protected equipment to the environment. The exposure of protected equipment to the environment may result in contaminants entering a system which may damage, degrade or quicken the failure of the system.
- Some implementations were conceived in light of the above, among other things.
- Some implementations can include a desiccant breather having an inner pipe having a top portion with a lip extending radially from the inner pipe, the inner pipe having a threaded portion and a top connector. The desiccant breather can also include an outer pipe having a diameter sufficient to accommodate the inner pipe, the outer pipe having a bottom connector and a cap. The desiccant breather can further include a desiccant breather body portion having a cavity configured to hold desiccant material. The lip of the inner pipe can have a diameter equal to or greater than a diameter of the outer pipe.

In particular, thedesiccant breather 100 includes atop connector 102, awing nut 104, acap 106, a desiccantbreather body section 108 and abottom connector 110. The desiccantbreather body section 108 is configured to support a desiccant material holder. - In an example operation, when the desiccant material holder supported by the desiccant
breather body section 108 needs to be replaced, thetop connector 102 can be disconnected from a line that may be connected to the top connector. Thetop connector 102 is designed to accept a quick connect fitting that will help prevent air from entering the equipment. Thewing nut 104 may be loosened and removed from the top portion of thedesiccant breather 100. The inner pipe (shown and described below in connection withFIG. 4 ) may then slide a distance in a downward direction (e.g., toward bottom connector 110), but be prevented from sliding completely through thedesiccant breather 100 as described below in connection withFIG. 4 . Once thewing nut 104 is removed, thecap 106 can be removed to expose a cavity within the desiccantbreather body section 108 that holds the desiccant material holder (e.g., 1200 shown inFIG. 12 ), such as a holder containing color changing silica gel desiccant beads. As described below, the inner pipe includes an inner seal (e.g., nitril o-ring 407) that drops below the air slots (shown as 408 inFIG. 4 ) in the perimeter of outer pipe to effectively seal the outer pipe when the inner pipe slides down while the desiccant material is being changed, thus preventing contaminants from entering any machinery connected to thedesiccant breather 100. - Once the desiccant material has been changed (e.g., old desiccant material removed and new desiccant material added), the
cap 106 can be replaced on thebody section 108 and thewing nut 104 can be refastened to the inner pipe to secure the cap and to also raise the inner pipe and expose the side openings of the outer pipe through which desiccated air can pass. -
